There's pretty unambiguous statistical evidence that it happens. The Asian Ivy League percentage has remained basically fixed for 20 years despite the college-age Asian population doubling (and Asian SAT scores increasing slightly).
Being south asian myself - I suspect that the high achieving immigrant-and-immigrant-descended populations gravitate towards technical fields and Ivy leagues for different reasons than American whites do. Coming from hardship and generally being less WEIRD, they psychologically share more in common with the middle class and even blue collar workers than the Ivy League upper class - they see it as a path to success rather than some sort of grand purposeful undertaking. (One of the Asian Professional community I participated in articulated this and other dif...
You're saying that if we randomly picked 22-31 year-olds, a disproportionate member would be eldest children? For that to work, there'd have to be more eldest children in that age-range than youngest. Given the increase in population, that is certainly plausible. You would expect more younger families than older families, which means that within an age range there would be a disproportionate number of older siblings (unless it's so young that not all of the younger siblings have been born yet) but it doesn't seem like it would be nearly that significant.

The first electric cars were made in the 1880s. Is Tesla Motors using old technology?
The Mars rovers use lots of new technology (the aerobraking system and "skycrane", to name one). NASA has certainly experimented with new propulsion technology like VASIMIR and ion drives, it's just that these are high-specific-impulse low-thrust platforms unsuitable for launch but good for maneuvering once in orbit. Not all aspects of a field will advance at the same rate. Compare processing power to battery capacity, for example.
Do you have any evidence that any of these things actually happen to a significant extent? Virtually everyone is able to distinguish claims about tendencies from absolute claims, even if they lack the knowledge to express this distinction formally. Here's Steven Pinker summarizing research on stereotypes:
...Moreover, even when people believe that ethnic groups have characteristic traits, they are never mindless stereotypers who literally believe that each and every member of the group possesses those traits. People may think that Germans are, on average, mo
Or writing in a manner that simply takes it for granted that black people are unintelligent and prone to crime.
If someone can't distinguish between a categorical statement ("all demographic X people have trait T") and a statement about statistical tendencies ("the demographic X average for trait T is N standard deviations below that of demographic Y") , I question their ability to contribute to any community that's based around rigorous thinking.
It doesn't repel "anyone whose experience disagrees", it repels anyone unwilling to hear opposing viewpoints. While having had different experiences may correlate with an unwillingness to hear opposing viewpoints, it's highly dubious that this correlation is strong enough to completely exclude the former category.
I have difficulty seeing how you can do biology beyond pure description ("Here's a species of bird with appearance X and behavior Y") while ignoring both genetics and natural selection. Doing cellular biology seems near-impossible if you can't mention DNA, while ecology is similarly linked to selection pressure.
I'm not actually that intelligent (IQ about 92 or 96 if I remember right)
This seems quite unlikely given your reasonably high-quality posting history. Is this number from a professionally administered test? Do you have a condition like dyslexia or dyscalculia that impairs specific abilities but not others?
What does this mean? Google isn't helping and the only mention I see on LW is this post.
